Error Message:
Msg 2729, Level 16, State 1, Line 2
Column ‘%.*ls’ in %S_MSG ‘%.*ls’ cannot be used in an index or statistics or as a partition key because it is non-deterministic.

Severity level:
16.

Description:
This error message appears when you try to use a non-deterministic column in a indec, statistic or as partition key.

Consequences:
The T-SQL statement can be parsed, but causes the error at runtime.

Resolution:
Error of the Severity level 16 are generated by the user and can be fixed by the SQL Server user. The statement cannot be run this way. You cannot create an index or statistic on a non-deterministic column.

Versions:
This error message was introduced with SQL Server 2000.

Example(s):
IF OBJECT_ID (‘dbo.v’, ‘View’) > 0
   DROP VIEW dbo.v;
GO
CREATE VIEW dbo.v
WITH SCHEMABINDING
AS
SELECT CONVERT(varchar, GETDATE(), 126) AS Dt;
GO

CREATE UNIQUE CLUSTERED INDEX CIX_v
    ON dbo.v (Dt);
GO

In the above example we try to create an index on the view dbo.v. Because the index should contain expression CONVERT(varchar, GETDATE(), 126) as index key which is non-deterministic, the error is raised.
